First to say Mike is responsive as I rarely saw he always answers very quickly anytime so it makes you confident
Then the location is almost perfect, if you have been in Bangkok before you understood that it's close to everything but not at the door of the nightly places so you can sleep very well.
Mike also provide a lot of advice it's great of your first time in BKK otherwise just don't read it haha
The only negative thing is some simple things missing inside the room (who is good size and condition) to have an amazing stay but I know I'm complicated I'm french sorry haha
Conclusion this is a very good place to enjoy Sukhumvit 11 close to transportation
